Brand new in box. This was a part ordered by a mechanic that was not used. ( turned out to be a bad current limiter) just delivered last week at 410.00 to me. I’m told it can’t be returned and is new in the box. Part no 6041h189 for a bonanza. 12/28 volt.

I think the 6041h189 is the 28v one, and the 187 is the 14v one. So this would be just for 28v planes.
